ADJUSTABLE SLIDING-DOOR SUFPORT.

{SPECIFICATION forming part of Letters Patent No. 748,787, dated January 5, 1904. Application filed J une 22, 1903. Serial No. 162,461. (No model.)

To all whom it may concern:

Be it known that I, THEODORE C. PROUTY, a citizen of the United States, and a resident of Albion, county of Calhoun, and State of Michigan, have invented a new and useful Improvement in Adjustable Sliding-Door Supports, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to supports for sliding doors, and particularly to that class of such supports which includes a track for rollers or hanger-wheels adjustable relatively to a horizontal plane.

The object of said invention is to provide such a support in which the track may be so adjusted by means of an eflicient and economical construction operated with facility.

Said invention consists of means hereinafter fully described, and particularly set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a front elevation of a portion of a sliding-door support embodying my invention detached from the door-casing. Fig. II represents a vertical sectional view of such detached support. Fig. III represents a broken elevational view of a longitudinally-slidable bar which actuates the track in the adjusting operation. Fig. IV represents a plan view of a portion of the support. Fig. V represents an elevational view of one of the supporting-plates included in-my said invention. Fig.VI represents a front elevation of a sliding door, a portion of a building to which it is attached, and my invention as applied thereto.

A plurality of plates A-three, as illustrated-are secured above the door-opening at equal intervals, each plate being formed with two upwardly extending cars a, forming a trough-like slideway for a longitudinallymovable bar B, seated therein, Figs. I and VI. Upward displacement of the bar is pre- Inent.

vented by a stud 00', provided with an overhanging head a and secured to the plate A, Fig. IV. The cars and studs of all the plates form a complete and substantially horizontal slideway in which the bar B may be. shifted endwise without becoming displaced from the plates. Each of the latter is provided with two vertically-alined slots a and a which form slideways for two rearwardly-projecting studs 0 and 0, respectively secured to sliding brackets 0, one such latter being mounted upon each plate, as shown. Stud 0 is provided with a head 0 overlapping the rear surface of the plate A adjacent to the said slot or and preventing the forward displacement of the upper bracket, end. The lower stud c is provided with a head 0 slightly less in diameter than slot a in which it slides. The lower portion of each bracket 0 is bent outwardly to form a recess, Fig. II, so as to admit the bar B,and in those portions of. the latter adjacent to said slots a are formeda series of inclined slots 19, the inclination of-the latter varying, as will hereinafter be explained. That portion of each stud 0 intermediate of its head and the bracket passes through and is of substantially the same diameter as its corresponding slot 2), so that a longitudinal movement of the bar B will effect a movement of the bracket transverse relatively to such bar movement-that is, a vertical sliding move- Adjacent to one end of said bar and fixed to the building is a plate D, formed with a horizontal barrel d and depressed groove (2, in which is loosely seated a screwrod D, the one end of which is pivotally secured to the adjacent end of bar B. Said plate is further formed with a transverse slot d which receives athumbmut d turning upon the screw D. that by turning the nut d the bar B has a longitudinal movement imparted to it. Assuming that the end of the bar B connected with rod D represents a fixed plane, the inclinations of the slots 12 vary directly as their distances from such plane, such variation being hence progressive from one bar end toward the other. It will therefore be seen that a longitudinal movement of the bar will impart a simultaneous upward movement of the brackets directly proportional to their respective distances from the said bar end.

It will hence be seen Each bracket is formed with two forwardly extending arms c 0 to which is secured a unitary track E. Such described movement of the brackets will therefore impart a tilting movement to said track, whereby it may be adjusted to assume various positions relatively to a given plane to efiect a required adjustment, as indicated in dotted lines in Fig. VI.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1. In a sliding-door support, the combination of a track, movable means for supporting same, fixed means for supporting said movable track-supporting means, a longitudinally-movable bar adjustably secured to said movable track-supporting means, and

arranged to vary the angular position thereof relatively to a horizontal plane.

2. In a sliding-door support, the combination of a track, means for supporting same, including a plurality of members movable transversely of the longitudinal axis of the track, fixed means for supporting said members, and means adjustably secured to said members for simultaneously actuating said members to move varying distances.

3. In a sliding-door support, the combination of a track, means for supporting same, including a plurality of members movable transversely of the longitudinal axis of the track, fixed means for supporting said members, and a movable bar engaging said members and arranged to simultaneously move same.

4. In a sliding-door support, the combination of a track, means for supporting same, including a plurality of members movable transversely of the longitudinal axis of the track, fixed means for supporting said members, and a movable bar constructed to engage and simultaneously actuate said members varying distances.

5. In a sliding-door support, the combination of a track, means for supporting same, including a plurality of members movable transversely of the longitudinal axis of the track, means for supporting said members, comprising a plurality of fixed plates, and slidable means so constructed as to engage and simultaneously actuate said members as to impart transverse movement thereto.

6. In a sliding-door support, the combination of a track, means for supporting same, including a plurality of members movable transversely of the longitudinal axis of the track, means for supporting said members, comprising a plurality of fixed plates, and slidable means so constructed as to engage and simultaneously actuate said members as to impart transverse movement thereto, the construction being such that the distance through which each member is so moved varies directly as its distance from a given point.

7. In a sliding-door support, the combination of a longitudinally-movable bar, a plurality of plates forming a slideway for said bar,'and a member slidably mounted in each such plate, and a track mounted upon such slidable members, said bar engaging the latter and arranged to impart a slidingmovement thereto.

8. In a sliding-door support, the combination of a plurality of slidable members, slideway-supports for same, a movable bar engaging such members and arranged to actuate them to slide, the direction of movement of such bar being transverse relatively to the direction of sliding of said members, and means for moving said bar.

9. In a sliding-door support, the combination of a plurality of slidable members, slideway-supports for same, a movable bar engaging such members, by means of a plurality of headed studs on said members and a plurality of inclined slots in said bar, and arranged to move said members distances increasing progressively from one end of the support toward the other, and means for moving said bar.
